BACKGROUND

Health care for elderly and mobility challenged patients is a continually evolving social issue as health care technology progresses and enables greater life expectancies. The emerging technology is continually challenged, however, by cost expectations in providing increasingly expensive technology to longer living patients.

Mobility challenged individuals, such as wheelchair-bound and/or elderly individuals, often require transportation to medical facilities for receiving medical care. Some patients are unable to travel to facilities, or encounter substantial hardships to do so. For some ailments and conditions, adequate care is provided on-site at a residence or care facility, due to readily available medical caretakers, equipment and supplies. Certain equipment, such as imaging devices, are defined by large, heavy appliances that are generally permanently installed in a facility. MRI (Magnetic Resonance Imaging) machines, for example, often occupy an entire room. In can be problematic for non-ambulatory or wheelchair/bed bound patients to gain access to imaging equipment since such appliances are generally deemed non-transportable fixtures.

SUMMARY

A mobility apparatus for an imaging appliance such as a panoramic radiograph machine allows single-operator transport for on-site usage with ambulatory challenged patients. A counterbalanced pivot interface integrates the imaging appliance with a motorized transport vehicle for disposing the appliance securely on the vehicle, while the counterbalanced pivot interface allows positioning to an operational upright orientation for on-site usage. The imaging appliance includes modifications to a stock appliance for adapting the pivot interface for mobility and for usage with ADA (Americans with Disabilities Act) affected patients, such as wheelchair and scooter bound individuals. The modifications include a truncated base and truncated vertical riser, coupled with a counterbalance mass on the vehicle to maintain stability in the deployed and transportable positions. The lowered vertical riser permits the imaging mechanism to descend to accommodate seated patients. The counterbalance mass offsets the truncated base and allows the transport vehicle to support the deployed appliance. The counterbalanced pivot interface permits transition from a deployed to a transportable, or stowed, position by pivoting the substantially vertical stance of the appliance to an angled, stowed orientation. The angled orientation provides stability during transport, yet disposes a center of gravity such that a pivoting return to the deployed (vertical) state may be performed by a single operating technician. The pivot interface braces a lower region of an elongated, vertical body of the appliance, and employs elongated braces and spacers on an inclined support surface on the vehicle for hinged support of the appliance while pivoted to the angled orientation for transport.

DETAILED DESCRIPTION

Depicted below is a particular configuration of the disclosed approach employing a panoramic radiograph machine as an imaging appliance and a motorized dolly as the transport vehicle. The imaging appliance represents a substantial expense, and secure handling and transport are therefore required. Further, single operator deployment capability is achieved by maintaining an incline of the transport vehicle around a center of gravity of the stowed imaging appliance. This avoids the need for a dead weight lift of the imaging appliance as it merely needs to be “tilted” to pivot into a secure vertical operating position.

The transport vehicle is a modified wheeled vehicle commonly referred to as a handtruck or dolly, available from conventional sources. In the examples shown, the transport vehicle is motorized using a rechargeable electric motor arrangement. Such handtrucks are configured to center a transport weight above main drive wheels for limiting a dead weight borne by the user. In configurations herein, the imaging appliance has a center of gravity substantially centered over the main drive wheels when in a stowed or retracted position. Visually, this takes the appearance of an angled rest position on the inclined bearing surface of the dolly.

Conventional uses of the transport vehicle include transport of heavy, substantially cubical or rectangular loads. The transport vehicle includes an angled planar protrusion, or plate, at a lower end and designed to extend under a bottom surface of the load to be transported. The plate angles backwards in a rotational manner to effectively tilt the load into an angled, balanced position on the transport vehicle bearing surface. Configurations herein modify the conventional transport vehicle to remove the plate for permitting installation of the interface device.

FIG. 1 is a perspective view of an interface device securing an imaging appliance to a transport vehicle. Referring to FIG. 1 , the interface device 100 is shown after fabrication and before attachment to the transport vehicle and imaging appliance, as will become apparent in the description and Figs. that follow. The device 100 includes an attachment plate 12 welded to a bottom plate 24. The bottom plate 24 extends in parallel communication with a base of the imaging appliance and perpendicular to the attachment plate 12. The bottom plate 24 may be formed from a length of stock angle iron bolted or welded to the inclined load bearing surface of the transport vehicle, discussed further below. Angle braces 16 extend from the attachment plate 12 and terminate substantially coplanar with the bottom plate 24. A shaft 22 extends through pivot blocks 26 secured to the attachment plate 12 and through elongated braces 20-1 . . . 20-2 (20 generally) for pivotal movement between the attachment plate 12 and elongated braces 20. The elongated braces 20 bolt to the transport vehicle, and a lateral spacing member 28 provides an offset from the transport vehicle for proper deployed positioning of the imaging appliance.

FIG. 2 is a prior art view of an imaging appliance operable for use with the device of FIG. 1 . Referring to FIG. 2 , the imaging appliance 50 includes an upright 5 and an overhead support 8. A scan assembly 3 includes an x-ray source 4 and an image sensor 7. A facemask 6 provides positioning for a patient's head between the source 4 and sensor 7 for rotation of the scan assembly 3 around the head of the patient. A base 9 includes mounting holes for permanent attachment to a floor, complemented by mounting holes and brackets at the rear for wall attachment, discussed further below. Configurations herein truncate the base 9 and reduce the height of the upright 5 for accommodating immobile and wheelchair bound patients by permitting the scan assembly to descend to an appropriate height.

FIG. 3 is a perspective view of the counterbalanced transport interface attaching an imaging appliance to a transport vehicle. Referring to FIG. 3 , the counterbalanced transport interface device 100 attaches an imaging appliance 50 to a transport vehicle 40 for transport, deployment and usage thereof. The counterbalanced transport interface device 100 allows pivoting of the imaging appliance 50 to allow transport and on-site deployment at a remote facility while maintaining stability of the appliance through counterbalanced weights and braces. Referring to FIGS. 3-5 , the counterbalanced transport interface 100 for the imaging appliance 50 includes the attachment plate 12 secured to a lower region of a lower telescoping portion 14 (upright) supporting a rotating scan assembly 52 of the imaging appliance. A plurality of elongated braces 20-1 . . . 20-2 (20 generally) are adapted for attachment to the transport vehicle 40, such that the elongated braces 20 are configured to bear a weight of the appliance 50 during pivoting between a vertical deployed position and an angled, stowed position. The transport vehicle has an inclined bearing surface defining the stowed position. A pivoting attachment 10 between the attachment plate 12 and the elongated braces 20 is adapted to pivot the imaging appliance 50 to a stowed position, in which the stowed position bears the weight on the pivoting attachment 10 and the transport vehicle 40. The stowed position allows hand guided, rolling transport of the appliance by a single operator via the motorized vehicle 40; alternatively a passive rolling assembly may be employed.

The pivoting attachment 10 is configured to bear the weight as the imaging appliance 50 is deployed by disposing the upright 14 substantially vertical for bearing the weight on a truncated base 18 and the transport vehicle 40. In this deployed position, the transport vehicle 40 is stabilized by a counterbalance mass 42 under the angled transport vehicle surface for limiting angular movement of the upright beyond the deployed, vertical position. The imaging appliance 50 might otherwise exhibit an unstable forward tendency when a rotating scan assembly 52 is extended forward during rotation.

Threaded rubber feet beneath the truncated base 18 position the height of the base such that the hinge stabilizes the upright in a substantially vertical position and the four rubber feet under the base 18 are aligned coplanar with the tires of the transport vehicle 40. A lateral spacing member 28 shims or adjusts the elongated braces 20 to align the hinge with the proper deployed vertical position, discussed further below.

Conventional transport vehicles such as handtrucks are designed to bear weight against an inclined surface for centering a center of gravity of the transported load over the wheels. Such positioning relieves the operator from bearing the load as the wheels tend to balance around the center of gravity. The transport vehicle has an inclined bearing surface defining the stowed position, and the attachment plate is positioned based on a center of gravity of the imaging appliance 50 in the stowed position. The transport vehicle 40 may have and adjustable incline, or may be fixed. An angle of inclination allows the load to be substantially centered over the wheels to bear the dead weight of the load. Generally, the stowed position results from a pivot of not more than 60 degrees. Typically, the stowed position is based on a center of gravity of the imaging appliance and is expected to be a pivot of substantially around 45 degrees. This allows an easier transition to the deployed, or vertical position because the operator does not need to lift the load from horizontal.

A stock transport vehicle often has a perpendicular plate extending from the inclined bearing surface prior to adaptation as described herein. This perpendicular plate is removed to accommodate the interface device.

FIG. 4 is an alternate perspective view from the transport vehicle. Referring to FIGS. 3 and 4 , in the example configuration shown, the counterbalanced transport interface 100 further includes a bottom plate 24 extending in parallel communication with the base 18 and perpendicular to the attachment plate 12, and at least one angle brace 16 between the base 18 and the attachment plate 12.

The pivoting attachment 10 further includes a shaft 22 and at least one pivot block 26, such that the shaft 22 extends through the elongated braces 20 and the pivot block 26 for rotational communication therewith, in which the pivot block 26 is secured to the attachment plate 12. The lateral spacing member 28 is disposed between the elongated braces and an inclined bearing surface 44 on the transport vehicle 40, such that the lateral spacing member 28 is in perpendicular orientation with the elongated braces 20 extending across the bottom of the inclined bearing surface 44, and having a stand-off thickness for disposing the pivot block 26 in a noninterfering position with the inclined bearing surface 44 for permitting rotation. Alternatively, the pivot blocks 26 may be mounded on an extension of the elongated braces 20 in a cantilever position extending beyond the inclined bearing surface 44.

FIG. 5 . shows the deployed imaging appliance. Referring to FIGS. 3-5 , the disclosed approach modifies a stock imaging appliance according to the counterbalanced transport interface device 100. In the therapeutic environment having imaging appliances operable for fixture installation at a treatment facility, the method for adapting an imaging appliance for on-site transport includes attaching the counterbalanced transport interface to the imaging appliance. The method involves reducing a height of a telescoping upright, in which the upright includes a lower portion 14 and an upper portion 15 adapted to dispose within the lower portion 14, thereby reducing a height of the lower portion 14 for permitting greater downward travel of the upper portion 15 as the upper portion supports the rotating scan assembly 52 of the imaging appliance 50. The base 18 of the imaging appliance 50 is truncated for permitting ambulatory assistive vehicles beneath the rotating scan assembly 52, thus allowing a wheelchair or scooter to be wheeled beneath the rotating scan assembly 52.

FIG. 6 shows the shaft and pivot mechanism including an offset adjustment on a stowed imaging appliance. The pivoting attachment utilizes the shaft 22 and at least one pivot block 26, such that the shaft extends through the elongated braces 201-6 and the pivot block 26 for rotational communication. The pivot block 26 is secured to the attachment plate 12 and bears the weight of the imaging appliance 50. Bushings 23 align the shaft 22 between the elongated braces 20, and a plastic washer 25 (FIG. 7 ) or other friction reducing ring is disposed between. A lateral spacing member 28 provides an offset for permitting rotation of the pivot blocks 26 and to set an appropriate height for the deployed imaging apparatus 50.

FIG. 7 shows the offset clearances of FIG. 6 in greater detail. Referring to FIGS. 6 and 7 , the lateral spacing member 28 between the elongated braces and the transport vehicle, defines an offset thickness based on a distance 28′ to an inclined surface bearing the deployed imaging appliance and a rotational clearance of the pivot blocks 26. As the pivot block 26 rotates, a lower edge 26′ clears the surface on the transport vehicle based on a sufficient offset distance 28′

FIG. 8 shows a telescoping upright of the imaging appliance. Referring to FIG. 8 , the upright 200 employs a telescoping mechanism to permit height adjustment of the rotating scan assembly 52. The telescoping upright includes a lower 14 and upper 15 portion for allowing the scan assembly 52 to dispose around the head of the patient. The disclosed imaging appliance 50 includes a modified telescoping upright for reducing a height of the imaging appliance in the deployed position, such that the reduced height disposes the rotating scan assembly 52 more proximate to the center of gravity and also requires less force to deploy to the vertical position. The reduced height serves the dual purpose of accommodating wheelchair bound patients and facilitating single technician deployment.

The modified telescoping upright 200 includes a truncated lower portion 14 for receiving an upper telescoping portion 15. The upper portion 15 travels up and down inside the lower portion 14 from a screw driven actuator 210. The actuator 210 employs a modified, truncated drive actuator 212 corresponding to the truncated lower portion. In the example configuration, the lower telescoping portion 14 is trimmed by about 8-9 inches, and the actuator 212 a corresponding amount.

As indicated above, conventional approaches employing a stock imaging appliance expect standing patient. Mobility challenged patients may be wheelchair bound and/or unable to stand. Accordingly, the rotating scan assembly 52 must travel downward by receiving the upper portion 15 within the lower portion 14. A drive actuator 210 rotates a threaded adjustment member 212 through a receptacle block 214 attached to the upper portion for disposing the upper portion 15 up and down. A ribbon conductor 220, attached to a side of the upper telescoping portion 15, transmits electrical signals for controlling a telescoping range of movement of the upper telescoping portion 15 into the lower telescoping portion 14. The ribbon conductor 220 is truncated or trimmed to correspond to the top surface 222 of the lower portion 14. In particular arrangements, the truncated ribbon conductor 220 includes a sensing strip 230 for providing position feedback based on varied electrical characteristics from the telescoping movement. The linear sensor 232 is responsive to the position of the sensing strip 232, such as by varied resistance, current or voltage, and determines the travel of the upper portion 15 Recalibration of the head unit 52 height may be performed to ensure correct operation.

FIG. 9 shows an elevation platform complementing the height clearance afforded by the telescoping upright of FIG. 8 . Referring to FIG. 9 , show an elevated inclination for adapting an elevation distance between a rotating scan assembly and a seated patient. An elevated platform, accessible by a removable ramp, has a predetermined height for allowing a wheelchair or other mobility enhancement beneath the rotating scan assembly 52. Various removable ramp assemblies may be provided, with the intent of permitting wheeled access to the elevated platform to allow the scan assembly 52 to be lowered for use with a seated patient. A single piece ramp or multiple ramps may be employed to engage with the elevated platform and provide wheeled access.

FIG. 10 shows a contour for engaging the elevation platform of FIG. 9 with the deployed imaging appliance. An elevated platform 300 has a contour 305 corresponding to the deployed imaging appliance. Indentations 310 accommodate the angle braces for flush placement of the platform 300 against the lower telescoping portion 14.

FIG. 11 shows an unfolded view of the elevation platform 300 of FIGS. 9 and 10 . The elevated platform 300 employs a foldable, hinged ramp 320 for facilitating wheelchair access when the platform 300 is deployed beneath the scan assembly.

FIG. 12 shows a counterbalance weight for stabilizing the imaging appliance. A counterbalance is affixed to a transport vehicle beneath the inclined bearing surface 44, such that a mass of the counterbalance offsets a downward forward rotation of the rotating scan assembly. The imaging appliance is then engaged with the transport vehicle via a counterbalanced transport interface having a pivoting attachment. A welded handle allows the operator to change from the stowed position to standing and operating position.

In a therapeutic environment having imaging appliances operable for fixture installation at a treatment facility, a system configuring an imaging appliance having a rotating scan assembly for on-site transport may provide for on-site usage via an articulated, spring loaded ramp disposed in a box truck and responsive to extend to a ground level for long distance, enclosed movement of the engaged imaging appliance and transport vehicle.

FIG. 13 shows an alternate configuration avoiding angle braces. In an alternate arrangement as shown in FIG. 13 , the interface device 100 has elongated braces 20-1 . . . 20-2 that extend the position of the pivot blocks 26-1 . . . 26-2 in a noninterfering arrangement with the inclined bearing surface so as to accommodate the positioning provided by the lateral spacing member. Referring to FIG. 13 , the shaft 22 is disposed either higher off the inclined bearing surface 44 and/or beyond the forward edge 45 of the bearing surface 44 so that the pivot blocks 26 may rotate between the stowed and deployed positions without interfering with the transport vehicle surfaces. FIG. 13 therefore depicts the pivoting attachment including the shaft 22 and at least one pivot block 26 configured to bear the weight of the imaging appliance as the imaging appliance is deployed by disposing the upright substantially vertical for bearing the weight on a truncated base of the imaging appliance 50. The elongated braces 20 have dimensions and mounting that dispose the pivot block 26 in a non-interfering rotational communication of the pivot blocks with the transport vehicle.

FIG. 14 shows an undeployed imaging appliance on the transport vehicle as in FIG. 13 , where the bottom plate extends in parallel communication with the base and perpendicular to the attachment plate such that angle braces are not needed, as the attachment plate is welded to the bottom plate, including an angle iron, and attached via bolting to the imaging appliance 50. Bolted attachment to the imaging appliance 50 provides sufficient strength and rigidity.

FIG. 15 shows a view of an alternate pivoting attachment having a modified elongated member 20. The pivoting attachment further comprises the shaft 22 and at least one pivot block 26 (typically 2), such that the shaft extends through pivot holes 23 in the elongated braces 20 and the pivot blocks 26 for rotational communication therewith. The pivot holes 23 are made at a distance or offset 128 from the inclined bearing surface 44 such that the pivot blocks may freely rotate. Alternatively, or in combination, the elongated braces 22 may dispose the pivot block distal from a lower edge of the transport vehicle for avoiding rotational interference based on a length of the pivot blocks extending to the lower edge 45, or even slightly beyond. The offset 128 is provided by the elongated braces having a height for disposing the pivot blocks at an offset from the transport vehicle for avoiding rotational interference. The elongated braces therefore provide a pivot hole 23 or bore for engaging the shaft 22 at an offset thickness of the elongated braces based on a distance to a transport vehicle surface bearing the deployed imaging appliance and a rotational clearance of the pivot blocks 26.

FIG. 16 shows a top view of the configuration of FIG. 13 , where the elongated braces 20 flank pivot blocks 26 adjacent and above the bearing surface 44. A bumper or bushing facilitates pivoting rotation of the shaft.

FIG. 17 shows a front, undeployed view of the device of FIG. 14 as the pivot blocks 26 support the imaging appliance 50 on the inclined bearing surface.

FIG. 18 shows a lower region of the deployed imaging appliance depicting noninterfering clearance of the pivot blocks, as the offset 128 maintains the pivot blocks 26 clear of the forward edge 45 and bearing surface 44.
